Trigonometric Limits Demo (sin t)/t and (1-cos t)/t

This example dynamically demonstrates the limits of (sin t)/t and (1-cos t)/t as t approaches 0, providing geometric intuition for limit calculations. Core math concepts include trigonometric limits, limit computation, and geometric visualization. GeoGebra commands/objects used for construction are Intersect, Circle, Point, Segment, OrthogonalLine, CircleSector, and CircleArc. Suitable for high school calculus students to understand the geometric meaning and computation of limits.
